Performing outbound CTI (obsid 60298). Solar proton flux is low (about 50) and declining slowly. 3-day Solar-Geophysical Forecast issued Mar 31 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be at low to moderate levels. Region 582 remains capable of producing M-class flares. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominantly quiet levels with periods of unsettled conditions for 1-3 April.
